I have just joined this forum to say a massive thanks to Becky, I stumbled across this post after my dash warning light came on my 2010 Leon ecomotive, my husband took it into work to diagnose it and it came back as the EGR valve, just as he was about to purchase the valve from the internet I sent him this post, to cut a long story short my car was bought from an independent garage, was just coming up to 69k miles, I have only had it 2 years, it had full seat service history up until me getting it (hubby did it in work as he works at a motor vehicle training college), had the emissions fix done last year, emailed Seat UK quoting the trustbuilding measure, they got back within 2 working days saying that I had to take it to a seat dealer for a diagnosis, phoned a dealer they quoted me 79 pounds, the lady said that it wouldn't be refundable if it came under the trustbuilding repair, so we took a punt and risked the 79 pounds even though we knew what the diagnosis was and knowing they could knock me back because of the service history, took it in the next day, end result they never mentioned the service history and are fixing the fault free of charge, never even charged us the 79 pounds and gave us a brand new courtesy car for the princely sum of 6 pounds, my car should be done today (5 days after the original email) and all for free, to say I'm happy is an understatement, I thought I was looking at a huge bill, the light came on less than a week after forking out for new tyres to get it through its MOT

so thank you all x
